ABSTRACT:
Method and apparatus for compensating for local temperature difference of a steel product which has been previously heated above room temperature because of the preceding operation such as rolling and which is to be heat-treated. Upper, lower and edge burners are arranged in opposed relationship with a path of travel and are selectively ignited depending upon the surface temperature distribution of the steel product detected before it enters the apparatus, in such a way that the steel product is heated uniformly to a desired temperature.
